Modeling the United States Unemployment Rate with the Preisach Model of Hysteresis
… systems with hysteresis, we use the Preisach model. A discussion of the Preisach model is given as well as a method for computing the hysteretic transformation of an input variable. The focus of this paper is hysteresis in economics, namely, unemployment. We consider essential time series …

Hysteretic response of articular cartilage to cyclic loading
… These findings can lead to the development of a hysteretic model for cartilage, which may be used in a clinical setting to establish a novel method for determining the state of disease of cartilage.

Monotonic and Cyclic Simulation of Screw-Fastened Connections for Cold-Formed Steel Framing
This thesis introduces an approach for modeling the monotonic and cyclic response of cold-formed steel framing screw-fastened connections in commercial finite element programs. The model proposed and verified herein lays the groundwork for seismic modeling of cold-formed steel (CFS) framing …

Neural-Network and Fuzzy-Logic Learning and Control of Linear and Nonlinear Dynamic Systems
… ship-motion simulation by means of a numerical model called LAMP, the modeling of fins and computation of the hydrodynamic forces produced by them, and a neural-network/fuzzy-logic controller. LAMP is based on a source-panel method to model the flowfield around the ship, whereas the fins are …

Modelling the Post-Peak Response of Existing Reinforced Concrete Frame Structures Subjected to Seismic Loading
… of shear failure. A novel shear hysteresis model is proposed employing these relationships, based on experimental observations that deformations after the onset of shear failure tend to concentrate in a specific member region. A computationally efficient finite element model of the …

Energy-Based Evaluation and Remediation of Liquefiable Soils
… by energy-based pore pressure generation models, which functionally relate dissipated energy to residual excess pore pressures. Assuming a linearized hysteretic model, a "simplified" expression is derived for computing the energy dissipated in the soil during an earthquake (i.e., Demand). …

Estimation of Earthquake Input Energy, Hysteretic Energy and its Distribution in MDOF Structures
… E as per IBC 2012 soil classifications) and four hysteretic models (bilinear plastic, stiffness degradation, bilinear flag and bilinear slip) are developed for five ductility levels (=1, 2, 3, 4, 5) using ground motion ensembles of 38, 42, 38 and 26 recorded at site classes B, C, D and E, …
